LINK. A

SPECIFICATION forming part of Letters Patent No. 267,834, dated November 21, 1882.

Application filed May 25, 1882. (Model.) I

To. all whom it may concern:

Be it known that I, WILLIAM BURTON, of Terre Haute, in the county of Vigo, and in the State of Indiana, have invented certain new and useful Improvements in Links; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

This invention relates to certain improvements in chain'links; and it has for its objects to provide a link constructed in two parts, pivoted together and so arranged that a series of the same may be secured together to form a chain, as more fully hereinafter specified. These objects I attain by the means illustrated in the accompanying drawings, in which Figure 1 represents a side elevation of one of my improved links, showing the parts opened out; Fig. 2, an edge view, and Fig. 3 a sectional view, ofone of the links.

The letter A indicates the two parts of the link, which are cut away at an incline on opposite sides and formed with shoulders B, loosely secured to each other by a rivet, the parts being adapted to swing together and form a link of the ordinary shape when closed.

The shoulders B O are cut on a bevel, as shown,

in Fig. 3, so as to aid in holding the two halves of the link together. The two halves of the 'links are duplicates of each other, each having a short arm, 0 G, and a long arm, 0 G. The long arms come opposite to each other when the link is closed. This peculiar construction enables a link to be formed, which, when closed, will be without a break on either side. As the shoulders B B and ends 0 G are cut at a bevel, they look together, and a much stronger link is the result than in one in which the rivet has to bear the entire strain in a lat- I eral as well as a longitudinal direction. Be

sides, a link formed in this manner shows a continuous smooth surface on both sides,thereby presenting the qualities and appearance of a welded link.

It will be seen that as thus constructed a series of the links may be connected. with each other, and when connected will hold together mutually, as the overlapping parts will prevent the slipping of one link from the other. Moreover, it will be perceived that the strain will not be on the rivets, but on the overlapping members of the links, forming a link having the strength virtually of a solid link.

The advantages of my improved link will be apparent without further description but among others it maybe mentioned, and will be evident, that the links as constructed may be fastened together to make a chain of any length without welding, or may be separated to shorten a chain or to introduce extra links without the employment of skilled. labor.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

A chain-link of elliptical form, composed of two halves, each half having flattened surfaces on its opposite sides cut at an angle, and with locking-shoulders, as shown, so that the link, when closed, presents a smooth continuous outer surface on both of its sides, in combination with the pivot It at one end, upon which each half turns, substantially as shown and described, and for the purposes set forth.

In testimony whereof I at'fix my signature, in presence of two witnesses, this 8th day of May, 1882.

hi WILLIAM BURTON.
